TENSION MECHANISEI FOR TICKET RIBBONS.

Application filed March 17, 1920. Serial N'o. 366,619.

To all whom it may concern:

Be it known that I, .JOSEDPHLF. DwYnn, a citizen of the United States,residing at Seattle, in the county of King and Stat of YVashington. haveinvented a certain new and useful Improvement in Tension. Liechanism forTicket Ribbons, of which thefollowing is a specification.

My invention relates to improvements in tension mechanism and the objectof my invention is to provide a tension mechanism that is adapted foruse in ticket dispensing machines to restrainingly engage the ticketribbon to prevent the same from being witln drawn too easily and whichalso prevents the ticket ribbon from being forcedback into the machinesubsequent to its withdrawal.

Another object is to provide a tension mechanism that embodiessimplicity and economy in construction, that is positive and efiicientin operationand that will not readily get out of order.

With the above and other objects in view which will appear as thedescription proceeds my invention resides in the novel construction,adaptation and arrangements of partshereinafter described and claimed.

I accomplish these objects by devices illustrated in the accompanyingdrawings, wherein Figure 1 is a vertical medial section of a ticketdispensing machine embodying my invention Fig. 2 is a top plan view ofthe same; and

Fig. 3 is an enlarged fragmentary View of my tension mechanism.

Referring to the drawings, throughout which like reference numeralsindicate like parts, the numeral designates the end walls of the casingof a ticket dispensing machine and 11 designates a substantiallysemi-circular wall section of the said casing thatis rigidly secured atits edges to the peripheral portion of th end walls lO'and which servesto hold the same in rigid spaced apart relation.

A hinged arcuate door 12 arranged to swing rearwardly formssubstantially the other half of the circular wall section of the casingand also serves to afford access to the interior of the ticketdispensing machine for the purpose of inserting new rolls of ticketribbon when necessary. A base bracket 1a inay be secured to a suitablesupport by stud bolts 15 and is also secured to the underside of thecasing ofthe ticket dispensing machine.

The upper end of the wall section 11 of the casing is formed with aflattened portion 16, a rounded or loopedportion 17, a gully portion 18and a shallow channel portion or shelf 19. r

The arcuate door 12 is provided adjacent its upper end with a tensionspring 20, a flat portion 21, a central rectangular opening 22 in theportion 21, a transparent plate 23, and a guide frame 2a.

The flattened portion 16 on the upper end of the wall section 11 issubstantially tangentially. disposed with respect to the periphery ofthe said wall section and provides a suitable support for the channelportion 19, the rounded portion 17 functions as a convenient guide rollfor the ticket ribbon 13,the gully portion 18 is formed to provide agully to which the ribbon 13 is caused to conform by the pressure ortension of the spring 20 on the door 12 bearing upon the same while thechannel portion 19 extends outwardly and downwardly to provide a supportand guide for the ribbon 13 as it passes over thesame. The outer end ofthe channel portion 19 may be provided with a notch to facilitategrasping the end of the ticket ribbon with the fingers.

,The tension spring 20 is fixedly secured on one end thereof to theinner face of thehinged arcuate door 12 adjacent its upper end, theouter or free end of said spring 20 being adapted to bear upon theribbon 13 at the points where it passes over the round portion 17 andwithin the gully portion 18 below the plane of the channel portion 19 torestrainingly engage the ribbon 13 and prevent the same from beingpulled outwardly too easily and also to prevent the ribbon 13 from beingforced back into the machine after it has once been pulled outwardlypast the outer end of the spring 20.

It will be obvious from the foregoing description taken in connectionwith Figs. 1 and 3 of the drawings that this construction provides for abreak or change in the course of the ticket ribbon 13 as it passes fromthe roll to the point of delivery so that should an attempt be made toforce the ribbon back into the machine the force exerted would beexpended in the plane of that i portion of the ribbon resting on thechannel the point of engagement of the outer end of the spring 20-withthe saidribbon which is below the plane of the channel portion 19 asshown.

It will be obvious from the drawings that the space between the upperf-ace of the end of the door .12 projects substantially tangentiallyfrom said door and is adapted to be normally superimposed upon thechannel portion 19 as more clearly shown in Figs. 1 and 3. r V

The central opening 22' in the flattened portion 21 with its associatedtransparent plate 23, that is secured to the upper face ot said'port-ion by the retaining frame 24: is provided for the purpose ofexposing theend of the ticket ribbon 13 to the view of prospectivepurchasers for approximately the length of one ticket as it :lies in'thechannel 19. The door 12 maybe provided with any suitable locking meansnot shown when desired.

From the foregoing description taken in connection with the accompanyingdrawings, the advantages of the construction and of the method ofoperation will be understood those skilled in the art to which theinvention relates, and while I have described the principle of operationof the invention, together with the device which I 'now consider to bethe best embodiment thereof,

such engagement with said raised portion that said portion and meanswill prevent retractive movement of the strip by manual thrust on thefree end of the strip. I

2. In a ticket dispensing device, acornpartm'ent for holding a ribbon oftickets, a bar secured to and depending from the top 'of "thecompartment and forming a guide over and on which the ribbon of ticketsis to be drawn, a guideway over which the free end of the ticket ribbonis to be drawn, said 'guideway having an end in adjacent spaced relationto said bar and downwardly curved, and a resilient finger secured to thetop of the compartment and projecting over said bar with its free endbearing on the ticket ribbon immediately above the downwardly curvedportion of said guideway, whereby such ticket ribbon is maintained in anon-straight form between the guide bar, and guideway.

In witness whereof, I hereunto subscribe my name this 11th day of MarchA. D. 1920.
